The paper aims at the special measure demands of external trajectory test in the conventional weapon experiment range, which is based on GJ-321 precise tracking trajectory measure system and combined with relevant measure devices, puts forward a new thought梟etwork real-time intersection measure.

An example of determining the working points for a chemical weapon destruction plant was presented.

Impact of chemical weapon destruction on the structure of lake zoohydrobiont community

Community structure of zoohydrobionts in the lake affected by chemical weapon destruction was studied for the first time.

The worldwide fallout of caesium-137 (137Cs) associated with the nuclear weapon tests during the 1950s and 1960s has provided a valuable man-made tracer for studies of soil erosion and sediment delivery.

Suicide bombing attacks have emerged as a lethal weapon in the hands of terrorist groups.

The problems of the exterior ballistic design, especially, the caliber selection are solved in this paper by applying approximation methods other than usual tabular solutions。 Here various factors affecting caliber selection are investigated, the principles in selecting "d" and "Cq" at different firing ranges and the available boundaries thereof suggested, the iterative formulas and differential formulas for the determination of calibers established, and finally the comprehensive criteria in the evaluation of...

The problems of the exterior ballistic design, especially, the caliber selection are solved in this paper by applying approximation methods other than usual tabular solutions。 Here various factors affecting caliber selection are investigated, the principles in selecting "d" and "Cq" at different firing ranges and the available boundaries thereof suggested, the iterative formulas and differential formulas for the determination of calibers established, and finally the comprehensive criteria in the evaluation of various design concepts defined。In addition, the caliber formula of minimum recoil is presented according to specific energy of impact.In solving the problems mentioned above, this paper, apart from usual methods in the past, considers simultaneously all the aspects: both interior and exterior ballistics, performance requirements and effectiveness of the weapon systems, and it still possesses the advantages of clearness in physical relations and easiness in calculation.

In the design of the automatic weapons, the after-effect coefficient β is a very important factor which has been studied by many scholars and therefore the resultant empirical formulas and theoretically calculated formulas have been found。However, there is certain difference between these calculations and real conditions。In this paper, these results are analyzed and the formulas which are closer to real conditions are given。Therefore, this paper isdivided into two parts: the analysis of the achievements...

In the nuclear stratigic anti-attack of the war, We must to give the probability distribution of the demaged numbers of the single target in the target system, in order to improve the killing effectiveness. In the past, one considered the all different conditions which may occur in the anti-attack when nuclear weapons is thrusted. Then, using the method of combination to give the probability distribution of the numbers for the demaged targets. This method is trubsome, especially when the numbers of the...

In the nuclear stratigic anti-attack of the war, We must to give the probability distribution of the demaged numbers of the single target in the target system, in order to improve the killing effectiveness. In the past, one considered the all different conditions which may occur in the anti-attack when nuclear weapons is thrusted. Then, using the method of combination to give the probability distribution of the numbers for the demaged targets. This method is trubsome, especially when the numbers of the target is large. For this reason, We introduce the idea of target state, then apply ChapmanKolmogorof eguation to calculate the transition probability of the state for the target system. We obtain the recursive algorithm, and the calculation is much simpler. In the end of this paper we consider the mathematical models of the target allocation problems. Usually, we may discuss these problems by means of programming method.
